HI,
I'm not an expert in this but I'll try to give some suggestions so that others could possibly follow your question. One is that, not technically, maybe you should post it in English to get more help here, or you can try the NI Chinese forum.
Your main question is how to use all the 8 counters on PCI6602 for pulse train generation of different width and delay.
There are examples of using 8 ctrs for edge counting somethere in the forum, you may search for it. So for pulse train generation, I'd say it's also possible. The counters should work independently so you don't need any interconnection. You can use digital triggers to "delay" a pulse train generation if I understand what you mean delay correctly. I don't think you need a source input for pulse train generation, you define the high/low time in the task.
Anyone please correct me if I'm wrong.
Best,
L
